[Paget's disease of the breast]. / La malattia di Paget della mammella.

Paget's disease of the nipple is a rare lesion that is not always associated with underlying breast cancer. The authors report three cases of Paget's disease; in two of the three patients examined, the disease became evident following the appearance of an erythematous and erosive lesion on the nipple and areola, but no clinical evidence of an underlying nodule. In both cases diagnosis was made by integrating cytological tests by apposition of the nipple with mammography. In the third case the disease became manifest following the onset of a lesion on the nipple and areola with the characteristics of chronic eczema in association with a retroareolar nodule, measuring 3 cm, with the mammographic characteristics of an infiltrating carcinoma. All three patients were treated by radical mastectomy modified according to Madden.

[The role of imaging diagnosis in the study of thyroid neoplasms]. / Ruolo della diagnostica per immagine nello studio delle neoplasie tiroidee.

The aim of this paper was to evaluate the role of imaging techniques and methods in the diagnosis of thyroid tumours. The main aim was to analyse the various imaging methods and to search for an integrated diagnosis based on clinical and laboratory evaluations and techniques such as fine needle aspiration biopsy for which imaging is used as a guide. The authors stress the importance of analysing the sensitivity of the various methods in preoperative staging. The methods examined here include: scintigraphy, ultrasound, fine needle aspiration biopsy, Doppler ultrasound, color-Doppler scan, TC and magnetic resonance.

[The clinico-instrumental assessment of the vascular status of the uremic patient for the making of a vascular access for hemodialysis]. / Valutazione clinico-strumentale del patrimonio vascolare del paziente uremico per la confezione di accesso vascolare per emodialisi.

For almost twenty years the Institute of General Surgery and Organ Transplant at Palermo Polyclinic has dealt with vascular problems arising during the preparation, monitoring and search for vascular access in uremic patients. For a number of years advantage has been taken of the vascular status in uremic patients; in fact, the possibility of creating a long-lasting and efficient vascular access also depends on the optimal use of the patient's vascular resources. The authors briefly describe the clinical and instrumental diagnostic strategy for the approach to a vascular access in uremic patients which must be correct and must respect the vascular resources of a "chronic" patient by definition, for whom hemodialysis is often the only prospect of therapy.
